Wave number is the reciprocal of wavelength and is wirtten as

\bar{n} = \frac{1}{\lambda }

 

Amplitude of transmitted wave -

A_{t}= \left ( \frac{2V_{2}}{V_{1}+V_{2}} \right )A_{i}

A_{t}=  amplitude of transmitted wave

- wherein

A_{r}= amplitude of reflected wave

V_{1}\; and \; V_{2} are velocity of wave in incident and transmitted wave.

A_{i}= amplitude of incident  wave.
